<p>NAIC has guidelines for investment clubs–aimed at adults, but has published several articles on starting investment clubs in high schools. Sorry I don’t have link. </p>
<p>My kids high school started a school store. It is run by parent volunteers and proceeds go to PTO. Perhaps if your school does not already have something like that, you could start one and split profits with school. They sell school supplies that might be needed on emergency basis (notecards, batteries, lead refills, paper, etc), school logo items, healthy snacks, and special requests from teachers. They open the store before school, during break, and at lunch.</p>
